The San Diego Fire-Rescue Department, with the help of the Heartland Fire & Rescue Department, extinguished a brush fire in a ravine near the intersection of Alvarado Road and College Avenue at around 4:30 p.m. yesterday afternoon. The SDF-RD reported structures vehicles were not in danger because of the fire.

Several San Diego State students witnessed the fire from outside their apartments.

“My roommate and I walked outside and the first thing we saw was ash falling all around us. There was a huge boom of smoke coming toward us too,” Mikayla Sivner, a French junior, said.

The fire, which was contained less than 30 minutes after it started, caused the Metropolitan Transit System trolley Green Line running through SDSU to temporarily shut down. The trolley restarted its route at approximately 5 p.m. after a helicopter unit extinguished the flames.
